Summary:
It's useful if we add additional attributed to nodes in the graph - it's easier to set the attribute on all nodes, even if the value would happen to be None.

When nodes are created without an explicit name, a name is generated for
it based on the target. In these cases, we need to avoid shadowing
builtin names. Otherwise, code like:
```
a.foo.bar
```
results in pretty-printed code like:
```
getattr = a.foo
getattr_1 = getattr.bar
```
While this is technically allowed in Python, it's probably a bad idea,
and more importantly is not supported by TorchScript (where `getattr` is
hardcoded).
This PR changes the name generation logic to avoid shadowing all
builtins and langauge keywords. We already do this for PyTorch
built-ins, so just extend that logic. So now the generated code will
look like:
```
getattr_1 = a.foo
getattr_2 = getattr_1.bar
```

This adds type annotations to all classes, arguments, and returns
for fx. This should make it easier to understand the code, and
encourage users of the library to also write typed code.

Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/42991
Have Node both be a record of the operator in the graph, and the
way we _build_ the graph made it difficult to keep the IR datastructure
separate from the proxying logic in the build.
Among other issues this means that typos when using nodes would add
things to the graph:
```
for node in graph.nodes:
node.grph # does not error, returns an node.Attribute object!
```
This separates the builder into a Proxy object. Graph/Node no longer
need to understand `delegate` objects since they are now just pure IR.
This separates the `symbolic_trace` (proxy.py/symbolic_trace.py) from
the IR (node.py, graph.py).
This also allows us to add `create_arg` to the delegate object,
allowing the customization of how aggregate arguments are handled
when converting to a graph.
